DECODER FOR REMOTE

CONTROLLER WITH FIVE

FUNCTIONS



DESCRIPTION

The chip can be used with the encoder RCT02 to provide a

complete control functions to the remote-controlled toy. The

RCR02

has five output pins corresponding with the five function

actions i.e, forward, backward, rightward, leftward and turbo. The

received signals are amplified by the three-stage amplifier, and

then

the

appropriate

amplified

signals

are

sampled,

fault-tolerantly checked and decoded to control the actions of the

remote-controlled toy.

There is an internal oscillator in the RCR02. By adding an

external resistor conveniently, the oscillator will be constructed.

The oscillator frequency can be adjusted by the external resistor.

The relative error between the frequencies of the two on chip

oscillators in the RCT02 and RCR02 must be less than ±25%.


